<p>Reports a <b>null</b> check followed by a method call that will definitely return <b>false</b> when  <b>null</b> is passed (e.g. <b>Class.isInstance</b>).
  Such a check seems excessive as the method call always returns <b>false</b>.
</p>
<p>Here is an example of a violation: </p>
<pre><code>    if (x != null && myClass.isInstance(x)) { ... }</code></pre>
<p>The quickfix changes this code to:</p>
<pre><code>    if (myClass.isInstance(x)) { ... }</code></pre>
